Definitions

  • the present invention relates to plant-protecting active ingredient mixtures having synergistically enhanced action and to a method of improving the growth of plants, comprising applying to the plants or the locus thereof at least three active ingredient components together.
  • Active ingredient I is fludioxonil. See, for example, the Pesticide Manual, 11th Ed. (1997), The British Crop Protection Council, London, page 566.
  • Active ingredient II includes metalaxyl; metalaxyl consisting of more than 70% by weight of the R-enantiomer; metalaxyl consisting of more than 85% by weight of the R- enantiomer; metalaxyl consisting of more than 92% by weight of the R-enantiomer; metalaxyl consisting of more than 97% by weight of the R-enantiomer; and mefenoxam (i.e., R-metalaxyl or metalaxyl-M) wherein the metalaxyl component is pure R-metalaxyl which is substantially free of S-enantiomer. See, for example, the Pesticide Manual, 11th Ed. (1997), The British Crop Protection Council, London, page 792; and the Pesticide Manual, 11th Ed. (1997), The British Crop Protection Council, London, page 794.
  • Active ingredient III is a strobilurin fungicide such as azoxystrobin, picoxystrobin, kresoxim-methyl, or a compound of the formula:
  • the inventive mixture I + II + III is suitable for foliar application in living crops of plants as well as, in particular, for dressing applications on plant propagation material.
  • the latter term embraces seeds of all kinds (fruit, tubers, grains), cuttings, cut shoots and the like.
  • One particular field of application is the treatment of all kinds of seeds, in particular the seed treatment of maize including field com, sweet corn and pop corn.
  • this invention also relates to a method of controlling fungi and improving the growth of plants, which comprises treating a site, for example a plant or a plant propagation material, that is infested or liable to be infested by fungi with a) the active ingredient I, with b) the active ingredient II, and with c) the active ingredient III, in any desired sequence or simultaneously.
  • ratios of 2.5 g: 1 g: 1 g: 1 g a.i./100kg or 2.5 g: 1 g: 2.5 g a.i./100kg or 2.5 g: 1 g: 5 g a.i./100kg or 2.5 g: 1 g: 10 g a.i./100kg of seed are suitable.
  • novel active ingredient mixtures I + II + III have very advantageous curative, preventive and systemic fungicidal properties for protecting cultivated plants.
  • said active ingredient mixtures can be used to inhibit or destroy the microorganisms that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time those parts of plants which grow later are also protected from attack by such microorganisms.
  • Active ingredient mixtures I + II + III have the special advantage of being highly active against diseases in the soil which mostly occur in the early stages of plant development.
  • Pathogens are mainly Pythium, Tilletia, Gerlachia, Septoria, Ustilago, Fusarium, Rhizoctonia (so-called "damping off complex").
  • the novel mixture is also active against Oomycetes such as Phytophthora, Plasmopara, Pseudoperonospora, Bremia etc. as well as against the Botrytis species, Pyrenophora, Monilinia and further representatives of the Ascomycetes, Deuteromycetes and Basidiomycetes classes.
  • Suitable target crops are especially potatoes, cereals, (wheat, barley, rye, oats, rice), maize, sugar beet, cotton, millet varieties such as sorghum, sun flowers, beans, peas, oil plants such as rape, soybeans, cabbages, tomatoes, eggplants (aubergines), pepper and other vegetables and spices as well as ornamental shrubs and flowers.
  • the active ingredient mixtures according to the invention are especially advantageous for seed treatment of maize (field corn, sweet corn, popcorn and related crops) as well as the seed of wheat and barley.
  • synergistically enhanced action of mixtures of components I, II and III manifests itself, for example, in lower rates of application, a longer duration of action and altogether higher crop yields. Such enhancements were not to be expected from the sum of the actions of the individual components.
  • Such advantageous properties are improved crop characteristics including: emergence, crop yields, protein content, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf color, less fertilizers needed, less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, enhanced plant vigor, increased plant stand and early germination; or any other advantages familiar to a person skilled in the art.
  • the active ingredient mixtures of formulae I, II and III can be used in the form of premix formulations or the active ingredients I, II and III can be applied to the area, plant or seed to be treated simultaneously or in immediate succession, if desired together with further carriers, surfactants or other application-promoting adjuvants customarily employed in formulation technology.
  • Suitable carriers and adjuvants can be solid or liquid and are the substances customarily employed in formulation technology, for example natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers.
  • the compounds of this combination are used in unmodified form or, preferably, together with the adjuvants conventionally employed in formulation technology. To this end they are conveniently formulated in known manner e.g. to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also by encapsulation in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomizing, dusting, scattering, coating or pouring are chosen in accordance with the intended objectives and the prevailing circumstances.
  • Advantageous rates of application of the active ingredient mixture are normally from 0.5 g to 400 g a.i./ha, or from 1 g to 250 g al/ha.
  • the rates of application are from 0.5 g to 500 g, from 1 g to 100 g, or from 5 g to 50 g a.i. per 100 kg of seed.
  • One method of applying a mixture of active ingredients of formulae I, II and III or an (agro)chemical composition comprising these active ingredients is foliar application.
  • an insecticide such as a phenylpyrazole including fipronil or a neonicotinoid including thiamethoxam, imidacloprid, thiacloprid, clothianidin, nitenpyram or acetamiprid
  • foliar application is foliar application.
  • the frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen (fungi).
  • the active ingredient mixture can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the active ingredients in solid form to the soil, e.g. in granular form (soil application).
  • the mixture of the active ingredients of formulae I, II and III may also be applied to plant propagation material, i.e. to seeds, tubers, fruit or other plant material to be protected (e.g. bulbs) (coating) by impregnating the seeds either with a liquid formulation of the fungicides or coating them with a solid formulation (with the optional addition of an insecticide such as a phenylpyrazole including fipronil or a neonicotinoid including thiamethoxam, imidacloprid, thiacloprid, clothianidin, nitenpyram or acetamiprid).
  • plant propagation material i.e. to seeds, tubers, fruit or other plant material to be protected (e.g. bulbs)
  • a solid formulation with the optional addition of an insecticide such as a phenylpyrazole including fipronil or a neonicotinoid including thiamethoxam, imidacloprid, thiacloprid, clothi
  • formulations are prepared in known manner, typically by intimately mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
  • extenders e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
  • Suitable solvents are: aromatic hydrocarbons, the fractions containing 8 to 12 carbon atoms, typically xylene mixtures or substituted naphthalenes, phthalates such as dibutyl or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins; alcohols and glycols and their ethers and esters such as monomethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethyl formamide, as well as vegetable oils or epoxidised vegetable oils; or water.
  • aromatic hydrocarbons the fractions containing 8 to 12 carbon atoms, typically xylene mixtures or substituted naphthalenes, phthalates such as dibutyl or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins; alcohols and glycols and their ethers and
  • the solid carriers typically used for dusts and dispersible powders are calcite, talcum, kaolin, montmorillonite or attapulgite, highly dispersed silicic acid or absorbent polymers.
  • Suitable granulated adsorptive granular carriers are pumice, broken brick, sepiolite or bentonite, and suitable non-sorptive carriers are typically calcite or dolomite.
  • suitable surface- active compounds are nonionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties.
